Steering Lock

I think the housing is just "peened" over the lock. Not much good really. Sure I could do better.

Recall when fitting a new steering lock to my Mk 3 850 it was just a press fit which worked OK.The problem Ihad was when keywas operatedthe lockingpin that drops downdid not line up exactly with the hole on the bitwelded to the frame and could not fully engage, so had to file a bit off the locking pin for it to slot in properly and enable key to be fully turned and removed.

The outer barrel has either one or two holes in it, if I remember correctly. What I did was to drill the triple clamp section at a point corresponding to one of the holes in the barrel and tap a thread for a grub screw that would anchor the outer barrel in place.

Advice required please. Before I paint my yokes I thought I'd check the fit of the new Steering lock (Part. No. 030175) for 1972 750 Commando (presently dismantled). It drops in place but I can't find any info on how it should be locked in place. There seems no mention of how its held in place in the 3 different manuals I own. There is no drilling in the yoke for a locking pin or screw. I think the old one that I removed (years ago so can't remember) may have been glued in place but is that normal? Has anyone come across this problem before?

If you look at Andover Norton site on the parts there is a picture showing the top yoke parts. It shows the lock assy and you can just make out a small roll pin in the picture. You will probably find like mine the pin has become part of the yoke. It was a bit of solid metal that came out of mine when I eventually found it and punched it out with a dowel pin punch. The originals may have used solid pins?

On my Mk3 the pin is viewed from under the top yoke on the right hand side. My old pin only showed up after cleaning metal with emery cloth could just make out outline of pin. Gave way to punch and big hammer. I tried to send picture but it would not go. If you would like picture my email is cwinsby@hotmail.co.uk

Whilst my yolks are from an early 1971 Commando, my tale of woe might give you something to think about. My steering lock barrel was loose in the top yolk. I locked the steering but unknown to me the bolt had butted up against the lug on the frame and was just riding over it. I completely forgot about the steering lock and set off home. Fine until I came to the first RH corner that required enough steering to allow the lock to do it's job, down I went, luckily out of sight of my mates and any other traffic. Since then the hole in my top yolk has been vacant. I can laugh about it now but at the time it cost me a few broken off bits and some pride.

Glad you sorted it out. I also manipulated and filed the barrel tumblers to be able to use my ignition key in the steering lock. One key operation now.

Don't tighten the grub screw too tight as the new lock outside materials are very weak castings.
